Definitions

  • This invention relates to snow-clearance equipment, more particularly to a snow-removing machine of the type having a raisable and lowerable sweeping brush, as well as to a method of operating such a machine.
  • a further object of this invention is to provide a particularly advantageous method of operating a snow-removing machine.
  • the improvement comprises a sweeping brush formed of a plurality of portions, the common raising and lowering movement of the individual sweeping brush portions, which are pivotable relative to one another in a vertical plane, being controlled by cylinder-piston units, and the piston acting upon the sweeping brush portions always being impinged upon by pressure opposite to the direction of movement.
  • a torsion bar connecting the various sweeping brush portions is provided as a further damping means.
  • the pistons of the cylinder-piston units are impinged upon at the points of application of the cylinder-piston units by differing pressures corresponding to the differing weights of the sweeping brush portions for the purpose of raising the sweeping brush portions, and on the opposite side of the pistons a counterpressure corresponding to the desired pressure on the ground is caused to act for the purpose of lowering the sweeping brush portions.
  • FIGS. 1-3 are a side elevation, a top plan view, and an end-on view of a snow-removing machine
  • FIG. 4 is a front elevation of a blower-sweeper unit
  • FIG. 5 is a side elevation of the blower-sweeper showing means for suspending the unit from a carrier vehicle, an outer arm for holding the sweeping brush, and a nozzle, adjustable in height, at the end of an air duct,
  • FIG. 6 is the same side elevation as FIG. 5 viewed directly before the middle of the unit, showing a middle brush suspension and drive, as well as a hydraulic lifting device,
  • FIG. 7 is a partial front elevation of the blower-sweeper showing air deflection means at the entrance to the air duct, a torsion-bar connection between the hydraulic lifting devices, and the vertically adjustable air nozzle with retractile spring,
  • FIGS. 8 and 9 are a side elevation and a top plan view, respectively, of the outer holding and lifting device for the sweeping brush
  • FIG. 10 is a perspective view of the sweeping brush and the blower
  • FIG. 11 is a diagram of the control system
  • FIG. 12 is an operation table.
  • the carrier vehicle illustrated in FIGS. 1 and 2 has a conventional steered front planetary axle 1 and a likewise steerable rear planetary axle 2 which is locked, i.e., disengaged, in mid-position but can be engaged at any time.
  • the engaging mechanism is so designed that depending upon the position of a control valve (not shown) in a cab 6, it is possible to shift to front-wheel steering, all-wheel steering, or crab steering. With all-wheel steering, the rear axle exactly follows the alignment of the front axle and thus compels the blower-sweeper to keep in the track of the vehicle even during cornering. When the driver shifts to crab steering, all four wheels are steered in the same direction, which leads to diagonal displacement of the entire vehicle. Obstacles can thus be avoided, and maneuvering is facilitated.
  • the chassis of the vehicle is designed as an inverted “U" chassis 3, so that in the region between front and rear axles 1 and 2, as high a clearance as possible is created between the chassis and the roadway.
  • the mechanical drive of rear axle 2 is transmitted to the latter from a distributor gear 4 via front and rear angular transfer gears 5.
  • a traction engine 7 Disposed in the area beneath cab 6 is a traction engine 7 followed by a multi-step automatic transmission from which the drive is transmitted to distributor gear 4 and thence to front and rear axles 1 and 2.
  • Distributor gear 4 and axles 1 and 2 have differential gear equalization with switch-in brakes.
  • the multi-step automatic transmission allows graduated working speeds, it being left to the driver to select a maximum speed, and also allows speeds of up to 80 kph for travelling to a new location.
  • a working engine 8 Disposed in the region above rear axle 2 is a working engine 8 which drives as necessary, via a distributor gear 9, two, or if need be more, hydraulic swivel piston pumps 10 and 11 with zero adjustment oil control, which in turn transmit the force via an axial-stroke pump 12 to a high-output radial-flow blower 13 and to a centrally disposed sweeping brush drive 14.
  • the speeds of rotation of blower 13 and of sweeping brush portions 15, 16 can be varied independently of one another, as need be, from a standstill up to a predetermined maximum speed of rotation and thus adapted to the prevailing conditions. These speeds of rotation are detected by pick-ups (not shown) and continuously indicated in cab 6.
  • snowplow 18 Disposed on a quick-change device 17 at the front of the vehicle is a snowplow 18 which can be raised, lowered, and swivelled to the left and right about a vertical axis by means of hydraulic lifting elements 19 and 20.
  • An elevation of snowplow 18 is shown in FIG. 3.
  • Chassis 3 and the body (omitted in FIG. 2) of the vehicle are designed so that any desired superstructural parts, e.g., a container for sweepings, a water tank, mowing equipment, etc., for other types of work, may be disposed over the entire space extending from behind cab 6 to the end of the vehicle.
  • any desired superstructural parts e.g., a container for sweepings, a water tank, mowing equipment, etc., for other types of work, may be disposed over the entire space extending from behind cab 6 to the end of the vehicle.
  • the vehicle is naturally equipped with parabolic springs on the front and rear axles, shock absorbers and transverse stabilizers, as well as a dual-circuit compressed-air power-braking system and spring-actuated parking brakes on all wheels.
  • the overall length of the vehicle, including the snowplow mounted at the front, is only about 10 m. With this compact construction, an outer turning radius of about 20 m. is possible with front-wheel steering, and about 12 m. when the all-wheel steering is engaged.
  • Snowplow 18 may be any of the usual commercially-available snowplows.
  • FIGS. 4, 5, and 6 illustrating the blower-sweeper unit
  • a ball-bearing ring mounting 22 is disposed in a three-point suspension 21 intended to be secured to chassis 3.
  • an air-supply pipe 23 designed as a bearing structure. Pipe 23 leads from the middle of the unit to the lateral ends left and right.
  • the air is conveyed by the turbine (radial-flow blower 13, FIGS. 1 and 2) via a pipe 51 through mounting 22, a bent pipe 24, and a nozzle 25 to an air duct 26 (FIG. 7) disposed in front of sweeping brush 15/16.
  • Nozzle 25 is adjustable in height by means of guide rails 27 and retractile springs (gas-pressure springs) 28 and can thus be moved in proximity to air duct 26 or else above that duct.
  • the entire adjustment, and particularly the force of retractile springs 28, is such that upon admission of an appropriate amount of air, nozzle 25 is automatically moved by the resultant build-up of pressure into the lower operating position and, when the supply of air is interrupted, by springs 28 into the upper resting position.
  • an air baffle 30 can be moved by means of a hydraulic cylinder 29 into a left-hand end position indicated in solid lines or a right-hand end position shown in dot-dash lines, thus deflecting the air supply from the turbine to air nozzle 25 either to the right or to the left.
  • a hydraulic cylinder 29 By means of another hydraulic cylinder (not shown), linked at one end to mounting 22 and at the other end to chassis 3, air duct 26 and sweeping brush 15/16 connected thereto can be moved at will about the vertical pivot point of ring mounting 22 into an operating position, shown in FIG. 2, to the left or to the right, or into any desired intermediate position.
  • FIGS. 8 and 9 An outer holding and lifting device for the sweeping brush is depicted in FIGS. 8 and 9. Disposed on a pivot bearing 31 situated below air-supply pipe 23, in the middle of the unit, is an endless chain drive 32 (FIG. 7), while lifting and holding arms 34 are rotatingly disposed on outer pivot points 33.
  • the sweeping brush composed of brush portions 15 and 16 is mounted to rotate freely in outer bearings 36 while being rotatingly integral with an arcuate spline-shaft section 35 (FIG. 6) projecting to the left and right from chain drive 32.
  • Sweeping brush 15/16 is raised into its travelling position and lowered into its operating position, where it is held with a constant pressure against the ground, by means of two double-acting hydraulic cylinders mounted between the sides of chain drive 32 and supports on pipe 23, and by two further double-acting hydraulic cylinders 37 mounted at the ends of pipe 23 between arms 34 and supports on pipe 23 (cf. FIG. 10).
  • Two torsion bars 38 (or only one) connecting pivot points 31 and 33 are provided for stabilizing and mutually supporting the lifting devices disposed at pivot points 31 and 33 but are so dimensioned that chain drive 32, serving as the middle lifting device, and the outer lifting and holding arms 34, may be independent of one another within a certain angular range and thereby enable optimum adaptation of brush portions 15/16 to the surface to be cleared, even when there are substantial irregularities and slopes or cambers.
  • the aforementioned constant pressure of brush portions 15/16 against the ground is ensured by means of the hydraulic system diagrammed in FIG.
  • Brush portions 15/16 may consist of disk- or strip-shaped brush segments, of steel wire or plastic.
  • Two-part sweeping brush 15/16 is hinged at three points and, in principle, suspended from three lever arms moved by means of differential hydraulic cylinders 37 with pistons 50.
  • Chain drive 32 takes care of the middle suspension, independently of the two outer suspensions 34, which operate with one cylinder each and are connected in parallel.
  • the air supplied by blower 13 is conveyed to the left-hand or right-hand nozzle 25, depending upon the position of air baffle 30.
  • nozzle 25 Owing to the pressure build-up of the air supplied, nozzle 25 is pushed down into its operating position against the bias of retractile spring 28 and rises into its resting position again when the air supply is interrupted. (This movement may be brought about hydraulically instead by substituting a hydraulic cylinder for spring 28 and connecting it in series with cylinder 29, for example. The appropriate right or left nozzle 25 would then automatically be lowered or raised upon reversal of air baffle 30.)
  • Working engine 8 and the working implements are operated and monitored electrically or electro-hydraulically from an additional operating panel in the cab.
  • the simple arrangement and the type of drive used, with automatic transmission, enable the driver to handle the machine easily without another operator.
  • the hydraulic drives of the radial turbine and the sweeping brushes are secured against overloading by the zero adjustment oil control of the swivel piston pumps.
  • blower-sweeper unit The mechanical attachment of the entire blower-sweeper unit by means of three-point suspension 21 and the hydraulic connections for the brush drive and for actuation of the hydraulic cylinders are laid out in such a way that they can be affixed to the carrier vehicle and dismantled easily and within a relatively short time.
  • the entire blower-sweeper unit rests on the ground by means of four auxiliary wheels having vertically adjustable shafts, and it can be pulled out from under the vehicle laterally.
  • Cylinder 37 is locked when directional control valves 44 and 48 are closed.
  • Oil at a pressure P 0 is supplied by a pump (not shown) over a pressure line 42 to control valve 44, where the slide opens the passage Y2.
  • the oil then flows through a pressure-reducing valve 45 and, with the pressure adjusted to P 1 , moves piston 50 of cylinder 37 downward.
  • the oil forced into the other chamber flows against the resistance P 2 of a pressure-reducing valve 47 through the passage Y3 and over a return line 49 to a tank (not shown) T.
  • a hydraulic pressure basin 43 is incorporated as an additional damping element and ensures the displacement and feed of the oil upon rapid movements of piston 50 in cylinder 37 even when the output of the pump is relatively low.
  • adjustable pressure-reducing valve 45 Through actuation of adjustable pressure-reducing valve 45, the desired pressure P 1 against the ground can be set as required.
  • Passage Y1 of control valve 44 is open.
  • the oil at pressure P 0 flows via check valve 46 into cylinder 37.
  • the displaced oil flows back into tank T via control valve 44.
  • Control valve 48 remains closed.
  • a snow-removing machine which ensures faultless snow clearance and, above all, a substantially increased rate of removal as compared with prior art machines, as well as steadily maintaining the desired pressure of the sweeping brush against the ground.
